description
The TSB41LV01 provides the digital and analog transceiver functions needed to implement a two-port node in
a cable-based IEEE 1394 network. The cable port incorporates two differential line transceivers. The
transceivers include circuitry to monitor the line conditions as needed for determining connection status, for
initialization and arbitration, and for packet reception and transmission. The TSB41LV01 is designed to interface
with a link layer controller (LLC), such as the TSB12LV22, TSB12LV21, TSB12LV23, TSB12LV31, TSB12LV41,
TSB12LV42 or TSB12LV01A.
The TSB41LV01 requires only an external 24.576 MHz crystal as a reference. An external clock may be
provided instead of a crystal. An internal oscillator drives an internal phase-locked loop (PLL), which generates
the required 393.216 MHz reference signal. This reference signal is internally divided to provide the clock
signals used to control transmission of the outbound encoded strobe and data information. A 49.152 MHz clock
signal is supplied to the associated LLC for synchronization of the two chips and is used for resynchronization
of the received data. The power-down (PD) function, when enabled by asserting the PD terminal high, stops
operation of the PLL.
